The outer frame 1-3 is disposed between the first outerframe 1-A1100, the second outer frame 1-B110, and the casing 1-2 afterthe first optical component 1-AS and the second optical component 1-BSare arranged in parallel, so as to prevent relative movement of thefirst outer frame 1-A1100, the second outer frame 1-B110, and the casing1-2, and an optical axis 1-AO of the first lens driving mechanism1-A1000 is parallel to an optical axis 1-BO of the second lens drivingmechanism 1-B100.

Please refer to FIG. 3, which is an exploded diagram of the first lensdriving mechanism 1-A1000 according to an embodiment of the presentdisclosure. In this embodiment, the first lens driving mechanism 1-A1000includes a first outer frame 1-A1100, a first driving assembly 1-A1200,a base 1-A1400, an image sensor 1-A1500. The first outer frame 1-A1100and the base 1-A1400 can form a hollow box, and the first outer frame1-A1100 surrounds the first driving assembly 1-A1200. Therefore, thefirst driving assembly 1-A1200 can be accommodated in the aforementionedbox. The image sensor 1-A1500 is disposed on a side of the box, thefirst light-entering hole 1-A1001 is formed on the first outer frame1-A1100, and the base 1-A1400 has an opening 1-A1410 corresponding tothe first light-entering hole 1-A1001. Thus, the light can reach theimage sensor 1-A1500 through the first light-entering hole 1-A1001, thefirst optical component 1-AS, and the opening 1-A1410 in sequence, so asto form an image on the image sensor 1-A1500.

The first driving assembly 1-A1200 comprises a lens holder 1-A1210, aframe 1-A1220, at least one first electromagnetic driving assembly1-A1230, at least one second electromagnetic driving assembly 1-A1240, afirst elastic member 1-A1250, a second elastic member 1-A1260, a coilboard 1-A1270, a plurality of suspension wires 1-A1280, and a positionsensing assembly (including a plurality of position detectors 1-A1290).

The lens holder 1-A1210 has an accommodating space 1-A1211 and a concavestructure 1-A1212, wherein the accommodating space 1-A1211 is formed atthe center of the lens holder 1-A1210, and the concave structure 1-A1212is formed on the outer wall of the lens holder 1-A1210 and surrounds theaccommodating space 1-A1211. The first optical component 1-AS can beaffixed to the lens holder 1-A1210 and accommodated in the accommodatingspace 1-A1211. The first electromagnetic driving assembly 1-A1230 can bedisposed in the concave structure 1-A1212.

The frame 1-A1220 has a receiving portion 1-A1221 and a plurality ofrecesses 1-A1222. The lens holder 1-A1210 is received in the receivingportion 1-A1221, and the second electromagnetic driving assembly 1-A1240is affixed in the recess 1-A1222 and adjacent to the firstelectromagnetic driving assembly 1-A1230.

The lens holder 1-A1210 and the first optical component 1-AS disposedthereon can be driven by the electromagnetic effect between the firstelectromagnetic driving assembly 1-A1230 and the second electromagneticdriving assembly 1-A1240 to move relative to the frame 1-A1220 or thefirst outer frame 1-A1100 along the Z-axis. For example, in thisembodiment, the first electromagnetic driving assembly 1-A1230 can be adriving coil surrounding the accommodating space 1-A1211 of the lensholder 1-A1210, and the second electromagnetic driving assembly 1-A1240can comprise at least one magnet. When a current flows through thedriving coil (the first electromagnetic driving assembly 1-A1230), anelectromagnetic effect is generated between the driving coil and themagnet. Thus, the lens holder 1-A1210 and the first optical component1-AS disposed thereon can be driven to move relative to the frame1-A1220 and the image sensor 1-A1500 along the Z-axis, and the purposeof auto focus can be achieved.

In some embodiments, the first electromagnetic driving assembly 1-A1230can be a magnet, and the second electromagnetic driving assembly 1-A1240can be a driving coil.

The first elastic member 1-A1250 and the second elastic member 1-A1260are respectively disposed on opposite sides of the lens holder 1-A1210and the frame 1-A1220, and the lens holder 1-A1210 and the frame 1-A1220can be disposed therebetween. The inner portion 1-A1251 of the firstelastic member 1-A1250 is connected to the lens holder 1-A1210, and theouter portion 1-A1252 of the first elastic member 1-A1250 is connectedto the frame 1-A1220. Similarly, the inner portion 1-A1261 of the secondelastic member 1-A1260 is connected to the lens holder 1-A1210, and theouter portion 1-A1262 of the second elastic member 1-A1260 is connectedto the frame 1-A1220. Thus, the lens holder 1-A1210 can be hung in thereceiving portion 1-A1221 of the frame 1-A1220 by the first elasticmember 1-A1250 and the second elastic member 1-A1260, and the range ofmotion of the lens holder 1-A1210 along the Z-axis can also berestricted by the first and second elastic members 1-A1250 and 1-A1260.

Referring to FIG. 3, the coil board 1-A1270 is disposed on the base1-A1400. Similarly, when a current flows through the coil board 1-A1270,an electromagnetic effect is generated between the coil board 1-A1270and the second electromagnetic driving assembly 1-A1240 (or the firstelectromagnetic driving assembly 1-A1230). Thus, the lens holder 1-A1210and the frame 1-A1220 can be driven to move relative to coil board1-A1270 along the X-axis and/or the Y-axis, and the first opticalcomponent 1-AS can be driven to move relative to image sensor 1-A1500along the X-axis and/or the Y-axis. The purpose of image stabilizationcan be achieved.

In this embodiment, the first driving assembly 1-A1200 comprises foursuspension wires 1-A1280. Four suspension wires 1-A1280 are respectivelydisposed on the four corners of the coil board 1-A1270 and connect thecoil board 1-A1270, the base 1-A1400 and the first elastic member1-A1250. When the lens holder 1-A1210 and the first optical component1-AS move along the X-axis and/or the Y-axis, the suspension wires1-A1280 can restrict their range of motion. Moreover, since thesuspension wires 1-A1280 comprise metal (for example, copper or an alloythereof), the suspension wires 1-A1280 can be used as a conductor. Forexample, the current can flow into the first electromagnetic drivingassembly 1-A1230 through the base 1-A1400 and the suspension wires1-A1280.

A circuit member 1-A1420 is disposed in the base 1-A1400, and theposition detectors 1-A1290 are disposed on the circuit member 1-A1420.The position detectors 1-A1290 can detect the movement of the secondelectromagnetic driving assembly 1-A1240 to obtain the position of thelens holder 1-A1210 and the first optical component 1-AS in the X-axisand the Y-axis. For example, each of the position detectors 1-A1290 canbe a Hall sensor, a magnetoresistance effect sensor (MR sensor), a giantmagnetoresistance effect sensor (GMR sensor), a tunnelingmagnetoresistance effect sensor (TMR sensor), or a fluxgate sensor.

In addition, the first optical component 1-AS may define an optical axis1-A0, and the position sensing assembly may also be used to sense thedistance that the first optical component 1-AS moves along the opticalaxis 1-AO.

Next, please refer to FIG. 4, which is an exploded diagram of the secondlens driving mechanism 1-B100 according to an embodiment of the presentdisclosure. The second outer frame 1-B110 of the second lens drivingmechanism 1-B100 has a hollow structure and has an opening correspondingto the optical component (the second optical component 1-BS). That is,the optical axis 1-BO of the second optical component 1-BS passesthrough the opening of the second outer frame 1-B110, so that the lightcan enter the second lens driving mechanism 1-B100 along the opticalaxis 1-BO.

As shown in FIG. 4, the second lens driving mechanism 1-B100 mainlyincludes a second outer frame 1-B110, a base 1-B120, a holder 1-B130, asecond driving assembly 1-B140, a frame 1-B150, a first elastic member1-B161, a second elastic member 1-B162, and a shape memory alloy drivingassembly 1-B170. The second outer frame 1-B110 and the base 1-B120 maybe assembled as a hollow case. Therefore, the holder 1-B130, the seconddriving assembly 1-B140, the frame 1-B150, the first elastic member1-B161, and the second elastic member 1-B162 may be surrounded by thesecond outer frame 1-B110, and thus may be contained in the case.

The holder 1-B130 has a hollow structure, and carries an opticalcomponent (such as the second optical component 1-BS in FIG. 2) with anoptical axis 1-BO. The frame 1-B150 is disposed on the base 1-B120, andfixed to the second outer frame 1-B110. In addition, the holder 1-B130is movably connected to the second outer frame 1-B110 and the base1-B120. To be more specific, the holder 1-B130 may be connected to theframe 1-B150 through the first elastic member 1-B161, the holder 1-B130may also be connected to the base 1-B120 through the second elasticmember 1-B162, and the first elastic member 1-B161 and the secondelastic member 1-B162 are metallic materials. Therefore, the holder1-B130 is movably suspended between the frame 1-B150 and the base1-B120.

The second driving assembly 1-B140 at least includes a first drivingcoil (the driving coil 1-B141), a first driving magnetic member 1-B1421,and a second driving magnetic member 1-B1422. The driving coil 1-B141 isdisposed on the holder 1-B130, and the first driving magnetic member1-B1421 and the second driving magnetic member 1-B1422 may be disposedon the frame 1-B150. When a current is applied to the driving coil1-B141, an electromagnetic driving force may be generated by the drivingcoil 1-B141 and the first driving magnetic member 1-B1421, the seconddriving magnetic member 1-B1422 to drive the holder 1-B130 and theoptical component (such as the second optical component 1-BS) carriedtherein to move along Z-axis (the optical axis 1-BO) relative to thebase 1-B120 or the second outer frame 1-B110. Therefore, the autofocus(AF) function is performed. Furthermore, the second driving assembly1-B140 includes the shape memory alloy driving assembly 1-B170 which isdisposed below the base 1-B120, and drives the holder 1-B130 and theoptical component carried therein to move along a direction that isperpendicular to the optical axis 1-BO (X-Y plane) relative to the base1-B120. Therefore, the optical image stabilization (OIS) function isperformed. Regarding the operation of the shape memory alloy drivingassembly 1-B170, a further description will be provided belowaccompanied by FIG. 5.

The metal wires 1-B172 are made of shape memoryalloys (SMA). Accordingly, the metal wires 1-B172 have certainplasticity. Therefore, each of the metal wires 1-B172 may individuallydeform along a horizontal direction (X-axis or Y-axis) according toelectric signals. Therefore, the position of the holder 1-B130 (shown inFIG. 4), which is disposed on the shape memory alloy driving assembly1-B170, may be controlled, and the optical image stabilization (OIS)function is performed.

Please refer to FIG. 2 and FIG. 6. FIG. 6 is a schematic diagram showingthe arrangement of the first lens driving mechanism 1-A1000 and thesecond lens driving mechanism 1-B100 according to an embodiment of thepresent disclosure. As shown in FIG. 2 and FIG. 6, the first lensdriving mechanism 1-A1000 and the second lens driving mechanism 1-B100are arranged in a first direction (for example, the X-axis), and thefirst driving magnetic member 1-B1421 has an long strip-shaped structureextending in the first direction.

It should be noted that, along the X-axis, there is no magnetic memberof any second lens driving mechanism 1-B100 between the first opticalcomponent 1-AS and the second optical component 1-BS. For example, thefirst driving magnetic member 1-B1421 is not disposed between the firstoptical component 1-AS and the second optical component 1-BS. Based onthe arrangement of the magnetic members described above, electromagneticinterference can be reduced, and the distance between the first opticalcomponent 1-AS and the second optical component 1-BS can be shortened,thereby improving the photographing quality.

Please refer to FIG. 7, which is a schematic diagram of an opticalcamera system 1-3 according to another embodiment of the presentdisclosure. In this embodiment, the first lens driving mechanism 1-A1000and the second lens driving mechanism 1-B100 are disposed in oppositedirections. The light enters the first lens driving mechanism 1-A1000along the −Z axis, and the light enters the second lens drivingmechanism 1-B100 along the Z-axis.

Based on the above configuration, the optical camera system 1-3 cancapture images in different angles, and the arrangement of the magneticmembers is similar to that of FIG. 5, thereby reducing electromagneticinterference and greatly reducing the occupied volume so as to achievethe purpose of miniaturization.

Please refer to FIG. 8, which is a schematic diagram of an opticalcamera system 1-4 according to an embodiment of the present disclosure.In this embodiment, the optical camera system 1-4 includes a first lensdriving mechanism 1-A1000, a second lens driving mechanism 1-B100, and athird lens driving mechanism 1-C100 arranged in the first direction (theX-axis). The third lens driving mechanism 1-C100 has the same structureas the second lens driving mechanism 1-B100 and is configured to hold athird optical component 1-CS. The third lens driving mechanism 1-C100also has a third outer frame 1-C110 and a third driving assembly (forexample, including a first driving magnetic member 1-C1421 and a seconddriving magnetic member 1-C1422). The rest of the structure and theoperation manner are the same as those of the second lens drivingmechanism 1-B100, and details are omitted herein.

As shown in FIG. 8, the arrangement of the magnetic members in theoptical camera system 1-4 is similar to that of FIG. 6, so thatelectromagnetic interference can also be reduced.

Next, please refer to FIG. 9, which is a schematic diagram of theoptical camera system 1-4 in another view according to an embodiment ofthe present disclosure. In this embodiment, a circuit pin 1-B180 of thesecond lens driving mechanism 1-B100, a circuit pin 1-C180 of the thirdlens driving mechanism 1-C100, and a circuit pin (the circuit member1-A1420) of the first lens driving mechanism 1-A1000 are all disposed onthe same side of the optical camera system 1-4.

The distance between the lens driving mechanisms in the X-axis can beshortened because there are no circuit pins (normally used for formingelectrical connections to the outside circuit) disposed on the adjacentsides of the lens driving mechanisms. In addition, the circuit pins aredisposed parallel to the arrangement direction (the X-axis) of thoselens driving mechanisms, so that processing efficiency can be improved,thereby lowering manufacturing costs.

Please refer to FIG. 10, which is a schematic diagram of an opticalcamera system 1-5 according to another embodiment of the presentdisclosure. The optical camera system 1-5 is similar to the opticalcamera system 1-4, and the difference between them is that that one ofthe lens driving mechanisms of the optical camera system 1-5 employs aperiscope lens driving mechanism (a fourth lens driving mechanism1-D1000).

In this embodiment, the first optical component 1-AS of the first lensdriving mechanism 1-A1000 is a wide-angle lens having a focal lengthwith one times magnification (a first focal length), the second opticalcomponent 1-BS of the second lens driving mechanism 1-B100 is a lenshaving a focal length with two times magnification, and a fourth opticalcomponent (the lens 1-D1120) of the fourth lens driving mechanism1-D1000 is a wide-angle lens having a focal length with three timesmagnification (a second focal length), so that the optical camera system1-5 can achieve three-stage optical zoom.

Please refer to FIG. 11, which is a cross-sectional view along line(1-A)-(1-A′) in FIG. 10 according to an embodiment of the presentdisclosure. As shown in FIG. 11, the fourth lens driving mechanism1-D1000 includes a lens unit 1-D1100, a reflecting unit 1-D1200, and animage sensor 1-D1300. An external light (such as a light 1-L) can enterthe fourth lens driving mechanism 1-D1000 through the firstlight-entering hole 1-D1001 and be reflected by the reflecting unit1-D1200. After that, the external light can pass through the lens unit1-D1100 and be received by the image sensor 1-D1300.

The specific structures of the lens unit 1-D1100 and the reflecting unit1-D1200 in this embodiment are discussed below. As shown in FIG. 11, thelens unit 1-D1100 primarily comprises a lens driving module 1-D1110 anda lens 1-D1120, wherein the lens driving module 1-D1110 is used to drivethe lens 1-D1120 to move relative to the image sensor 1-D1300. Forexample, the lens driving module 1-D1110 can comprise a lens holder1-D1111, a frame 1-D1112, two spring sheets 1-D1113, at least one coil1-D1114, and at least one magnetic member 1-D1115.

The lens 1-D1120 is affixed to the lens holder 1-D1111. Two springsheets 1-D1113 are connected to the lens holder 1-D1111 and the frame1-D1112, and respectively disposed on opposite sides of the lens holder1-D1111. Thus, the lens holder 1-D1111 can be movably hung in the frame1-D1112. The coil 1-D1114 and the magnetic member 1-D1115 arerespectively disposed on the lens holder 1-D1111 and the frame 1-D1112,and correspond to each other. When current flows through the coil1-D1114, an electromagnetic effect is generated between the coil 1-D1114and the magnetic member 1-D1115, and the lens holder 1-D1111 and thelens 1-D1120 disposed thereon can be driven to move relative to theimage sensor 1-D1300, such as moving in the X-axis or the Y-axis. Inaddition, the lens unit 1-D1100 can further include a position sensingcomponent 1-D1116 configured to sense the movement of the lens holder1-D1111 relative to the frame 1-D1112.

The reflecting unit 1-D1200 primarily comprises an optical member1-D1210, an optical member holder 1-D1220, a frame 1-D1230, at least onefirst hinge 1-D1250, a first driving module 1-D1260, and a positiondetector 1-D1201.

The optical member holder 1-D1220 can be pivotally connected to theframe 1-D1230 via the first hinge 1-D1250. Since the optical member1-D1210 is disposed on the optical member holder 1-D1220, when theoptical member holder 1-D1220 rotates relative to the frame 1-D1230, theoptical member 1-D1210 disposed thereon also rotates relative to theframe 1-D1230. The optical member 1-D1210 can be a prism or a reflectingmirror.

The first driving module 1-B1260 can comprise a first electromagneticdriving assembly 1-B1261 and a second electromagnetic driving assembly1-B1262, respectively disposed on the frame 1-B1230 and the opticalmember holder 1-B1220 and corresponding to each other.

For example, the first electromagnetic driving assembly 1-B1261 cancomprise a driving coil, and the second electromagnetic driving assembly1-B1262 can comprise a magnet. When a current flows through the drivingcoil (the first electromagnetic driving assembly 1-B1261), anelectromagnetic effect is generated between the driving coil and themagnet. Thus, the optical member holder 1-B1220 and the optical member1-B1210 can be driven to rotate relative to the frame 1-B1230 around thefirst hinge 1-D1250 (extending along the Y-axis), so as to adjust theposition of the external light 1-L on the image sensor 1-B1300.

It should be noted that the direction (for example, along the X-axis) ofthe incident light entering the fourth optical component (the lens1-D1120) is different from the direction (for example, along the Z-axis)of the incident light entering the first optical component of the firstlens driving mechanism 1-A1000.

The position detector 1-D1201 can be disposed on the frame 1-D1230 andcorrespond to the second electromagnetic driving assembly 1-D1262, so asto detect the position of the second electromagnetic driving assembly1-D1262 to obtain the rotation angle of the optical member 1-D1210. Forexample, the position detectors 1700 can be Hall sensors,magnetoresistance effect sensors (MR sensor), giant magnetoresistanceeffect sensors (GMR sensor), tunneling magnetoresistance effect sensors(TMR sensor), or fluxgate sensors.

In some embodiments, the first electromagnetic driving assembly 1-D1261comprises a magnet, and the second electromagnetic driving assemblycomprises a driving coil. In these embodiments, the position detector1-D1201 can be disposed on the optical member holder 1-D1220 andcorresponds to the first electromagnetic driving assembly 1-D1261.

In addition, it should be noted that the arrangement of the lens drivingmechanisms in the optical camera system 1-5 can also achieve the purposeof reducing electromagnetic interference.

Please refer to FIG. 12, which is a schematic diagram of an opticalcamera system 1-6 according to an embodiment of the present disclosure.In order to improve space utilization, in this embodiment, the lensdriving mechanisms are arranged in an L-shaped manner. Furthermore, asshown in FIG. 12, the magnetic member (the first driving magnetic member1-B1421 or the second driving magnetic member 1-B1422) is not disposedon the adjacent side of the second lens driving mechanism 1-B100 and thefirst lens driving mechanism 1-A1000, and therefore the problem ofelectromagnetic interference can be reduced.

In addition, in other embodiments, one second lens driving mechanisms1-B100 of the optical camera system 1-6 may also be replaced by thefourth lens driving mechanism 1-D1000 to obtain different photographyeffects.

Please refer to FIG. 13, which is a bottom view of an optical camerasystem 1-6 according to an embodiment of the present disclosure. Asshown in FIG. 13, the circuit pins (the circuit member 1-A1420) of thefirst lens driving mechanism 1-A1000 are disposed on two adjacent sidesof the first outer frame 1-A1100 so as to make it easier for theoperator to solder the optical camera system 1-6 on the main circuitboard of the electronic device 1-0. In addition, as shown in FIG. 13,the circuit pins are not disposed on two adjacent sides of the two lensdriving mechanisms.

Please refer to FIG. 14, which is a schematic diagram of an opticalcamera system 1-7 according to an embodiment of the present disclosure.In this embodiment, the optical camera system 1-7 includes two firstlens driving mechanisms 1-A1000 and two second lens driving mechanisms1-B100. Furthermore, based on the configuration of the driving magneticmembers in this embodiment, the problem of electromagnetic interferencecan also be reduced.

Image processing can be performed by the processing circuit 1-X for theplurality of optical camera systems provided in the present disclosureto obtain better shooting quality. For example, when the electronicdevice 1-0 is equipped with an optical camera system having three lensdriving mechanisms (for example, the optical camera system 1-4), thefirst lens driving mechanism 1-A1000, the second lens driving mechanism1-B100 and the third lens driving mechanism 1-C100 can respectivelyobtain a first image, a second image, and a third image. When the lightsource is insufficient, the image captured by single lens drivingmechanism may not be clear enough, and the processing circuit 1-X cancomposite the first, second, and third images to obtain a clearcomposite image. This image processing method can shorten the exposuretime of the optical camera system and reduce the chance of beingdisturbed (the external influence such as shake, instantaneous stronglight, etc.).

In another embodiment, when the first lens driving mechanism 1-A1000,the second lens driving mechanism 1-B100, and the third lens drivingmechanism 1-C100 all photograph the same object or scene, the processingcircuit 1-X can be configured to compare the first image, the secondimage, and the third image. When a graph is included in the first imagebut is not included in the second image and the third image, theprocessing circuit 1-X determines that the graph is a noise, and removesthe graph in the composite image.

In another embodiment, the aforementioned lens driving mechanism cancapture a monochrome image. For example, the first image, the secondimage, and the third image respectively include red light information,blue light information, and green light information. Then, theprocessing circuit 1-X composites the first image, the second image, andthe third image into a color image.

In another embodiment, at least one of the first image, the secondimage, and the third image is a color image, and at least one of thefirst image, the second image, and the third image is a black and whiteimage. Then, the processing circuit 1-X composites the first image, thesecond image, and the third image into a color image. This compositecolor image is clearer than a color image captured by one single lensdriving mechanism.

Referring to FIG. 15, which is a side view of the electronic device 1-0according to another embodiment of the present disclosure. In thisembodiment, the optical camera system 1-4 may further include aninfrared light source 1-R configured to emit infrared light. Theinfrared light source 1-R can emit a diffused light 1-RS to serve as alight source for photographing. In addition, the infrared light source1-R may also include an adjustment component 1-RJ, so that the infraredlight source 1-R can emit a parallel beam 1-RP for depth sensing.

In this embodiment, at least one of the first image, the second image,and the third image captured by the optical camera system 1-4 mayinclude infrared light information. In the situation of insufficientlight source, the composite image can be clearer by compositing theinfrared image.

In addition, infrared light can also be used for depth sensing, and theprocessing circuit 1-X processes the composite image according to thesoftware calculation so as to enhance the image effect.

Next, please refer to FIG. 16, which is a diagram of a first image 1-GA,a second image 1-GB, and a third image 1-GC according to an embodimentof the present disclosure. The diagram on the left side in FIG. 16 showsthe first image 1-GA, the middle diagram shows the second image 1-GB,and the diagram on the right side shows the third image 1-GC. The firstlens driving mechanism 1-A1000 having a focal length (the first focallength) with one times magnification photographs the object 1-OJ togenerate the first image 1-GA, and the second lens driving mechanism1-B100 having a focal length (second focal length) with two timesmagnification photographs the object 1-OJ to generate the second image1-GB, and the fourth lens driving mechanism 1-D1000 having a focallength (the third focal length) with more than three times magnificationphotographs the object 1-OJ to generate the third image 1-GC.

The third image 1-GC corresponds to one region 1-RC of the second image1-GB or of the first image 1-GA, and the second image 1-GB correspondsto one region 1-RB of the first image 1-GA. The processing circuit 1-Xcan composite the three images according to the third image 1-GC. Forexample, the processing circuit 1-X composites the region 1-RC in thefirst image 1-GA, the region 1-RC in the second image 1-GB, and thethird image 1-GC, thereby increasing the local details of the compositeimage.

In addition, in some embodiments of the present disclosure, becausethere is a distance between two lens driving mechanisms of the opticalcamera system, the two images which are captured have parallax, andtherefore the processing circuit 1-X can composite the two images into a3D stereo image.

The present disclosure provides an optical camera system disposed in anelectronic device, and the optical camera system has a plurality of lensdriving mechanisms that can be arranged in different manners so as toobtain different photography effects. In an embodiment, the first lensdriving mechanism and the second lens driving mechanism are arranged inthe first direction and there is no magnetic member of the second lensdriving mechanism disposed between the first optical component and thesecond optical component. Thus, the problem of electromagneticinterference can be avoided.

In addition, in another embodiment, the plurality of lens drivingmechanisms may have different focal lengths, and they can photograph thesame object to obtain a plurality of images. Then, the images arecomposited by the processing circuit to obtain a clearer compositeimage.

As shown in FIG.24, a guiding slope 2-108C may be formed on one end of each of theextending portions 2-108E and the guiding slope 2-108C is configured toguide the optical component 2-LS when the optical component 2-LS (thecamera lens) is installed in the holder 2-108 so as to improveconvenience of assembly.

It should be noted that the number of extending portions 2-108E is notlimited thereto. In other embodiments, the holder 2-108 may only includetwo extending portions 2-108E that correspond to the diagonal corners ofthe fixed assembly.

Please refer to FIG. 25, which is a top view of the optical componentdriving mechanism 2-200 according to another embodiment of the presentdisclosure.
